Analyzer

Analyzer 2.5 – now available with full support for iOS 8! It comes with Audiobus 2.x support including Audiobus state saving, Inter-App Audio support, a great graphic engine and unbelievable usability and functionality!

The Analyzer is a combination of a sound pressure level (SPL) meter and a full range multiple bands frequency analyzer. It is mainly designed for audio professionals who need to evaluate different working environments (e.g. studios, live stages)… that’s why it’s perfect for anyone who’s in need of acoustical analysis!! It is easy to use and comes with amazing features only known from professional acoustic tools.

Use the Analyzer for measuring stages, testing speakers, evaluate sound mixing environments, analyzing your instrument… or the noise your neighbor makes with his new stereo!

Combine the Analyzer with external microphones such as the Gefell M372 or the Mic-W i436 for better measurement performance! Or use it with external USB audio hardware like Apogee’s One, Duet and Quartet, the RME Fireface UCX or the Alesis IO dock, change the measurement scale to dB FS and use it as a studio Analyzer! Use the built-in signal generator for measurements – even wireless via Airplay!

I want to use Analyzer in 1/3 Octave mode (Terzband), but the displayed frequencies numbers below the graph are a mess. What are these frequencies?
For acoustic measurements, the 1/3 Octave band CENTER frequencies should be displayed (according to EN ISO 266)! These are the ones that can be adjusted by graphic-Equalizers!
So, Please update the display, otherwise the app is totally useless for acoustical measurements/adjustments on stage.

Hi Andy,
Analyzer 2.0 let’s you switch the “center” frequency between 440 and 1000Hz and it will be available very soon! The frequencies you are used to are the ones based on center of 1000Hz – give it a few days and you will have them!

I have updatet to version 2.0, and the update installed, but ruined my app in OS 5.1.1.
Im not planning to update to IOS 6, and would like to use the old app or get a app that funktions with IOS 5 as promised

due to the many requests of iOS5 users we will make the App iOS5 compatible with the next update. BUT: in iOS5 there’s the limiter and the lowcut – we don’t think it’s clever to renounce of the huge advantages of iOS 6. We will make the App work in IOS5 but there’s no guarantee that all calibration works as well as in iOS6.

Hi,
I bought the Analzer 2.0 but i’m not able to a activate the spectrum analyzer . When I start the app the SPL Meter will launched Subsequently at once. Afterwards it’s impossible to activate the spectrum analyzer functionality. Maybe I do an operator error ?
Thanks in advance for your help

on iPhone the Analyzer view is available in landscape view. Make sure you turned off autorotation lock and turn your iPhone to landscape view – and there’s the Analyzer view. We built in an autorotation lock in both views for more practical handling – so maybe this caused your problem. It’s the white rotation symbol with/without a lock.

here are the answers:
– Is the calibration of the mic on the 4S affected by the use of an Otterbox Defender protective case?
I think so because it shades the mic. How massive the influence is we can not know because we don’t have such a case and can not measure it. But if you can lay your hands on a simple SPL Meter you can measure the difference by yourself.

What us the freq response spec on the 4S internal mic?
– The microphones are not linear on the whole frequency range. We offer compensation curves for this.

– Can I use the internal mic at the same time as I use the signal generator output through a cable? My first attempt shut off the mic!#%*!
No you can’t – iOS does not allow this because it is the headset input you’re using and it automatically shuts off the internal mic the moment you use this jack. There are possibilities though when using an external mic like i436 with splitter cable.

I am not using the headset output on the iPhone, I am using a cable from the big flat socket which has a 3.5mm stereo plug on the other end! Is the sig gen output from the headset jack different than the SUV gen output from the big (30-pin?) socket!?

the compensation curves for built-in mics are always integrated since Analyzer 2.0. So if you buy the Analyzer there’s an option to activate the compensation in the settings -> frequency compensation menu.

Im thinking about buying this app, I will use it with a Shure SM57, will it work? connecting it through USB.
I have the freq response of this mic, would I be able to manage the frequency response compensations for it? Or you only have the set up for the MicW ones?
Thanks!!!

thanx for the input, we will see what we can do. For identifying peaks the Analyzer offers an automatic peak detection: touch the workspace icon (upper right corner the left white icon), choose “caption” -> peaks. Now the Analyzer shows the topmost 3 peak levels with corresponding frequencies. For getting detailed information about the frequency response of a system it’s great to use the Leq function. In combination with a stationary noise (pink or white noise) you’ll get a really good response in a minute. If you now store this Leq graph you can compare it to previous and / or future measurements.

Some calibration mics for iPhone/iPad come with unique serialized calibration files that work with some analyzer apps. Does your app support calibration files or is MicW the only external mic directly supported?

At the moment we are offering freqeuncy compensations only for MicW Products. But we are working on cooperations with some other external mics as well – hopefully they will be available very soon. Calibration files are not supported.

The scales are logarithmic: they show dB (SPL or FS) on vertical scale (dB is logarithmic) and frequency (logarithmic) on horizontal scale. And if you export we don’t change this – every exported png or csv has logarithmic scale!

sorry for the trouble. There’s a problem with the Analyzer and iOS 5.1.1 which will be solved in the next Update (v2.3.1). It is already in review at iTunes, so it should not take more than a few days to get it all working again!

Is it possible to fix the frequency scale whilst increasing the resolution of the amplitude. I.e. to be able to zoom in whilst being able to see the whole frequency spectrum. Also is it possible to more clearly mark the frequency scale.

the zoom function appies always to both power and frequency. But you can try the lens function: touch and hold and you get it. It’s not possible to adjust the calse color but you can change the backgroundcolor and the color pf the graphs…#

Hi I’m a guitar builder and I’m thinking about buying you analyzer. I don’t have much experience with them. I want to be able to trigger the sampling by tapping my guitar and i want to be able to average 5 – 10 samples and display the frequency content of these averaged taps. Will your analyzer do this? Thanks!

Love the app and my apologies if this has been posted before. The app is not reading audio. I have checked my settings and the iPhone 5S mic is on in the app. I have cycled the phone on and off with no results. Oh wait I just plugged it into my computer. It is now responding. Any suggestions.
Thanks Syd

I’m considering to buy yor App Analyzer, but first i would like to know if it has been tested in the IPad III under iOS 8. I had a bad experience with other SPL and RTA analyzer, that after updating to IOS 8 has an erratic behavior likely because of problems with the internal mic calibration in this specific model
Another question the in-App buy hardware options, like microphones is possible in Spain
Please answer as soon as possible

there are indeed problems with iOS 8 and calibration levels – but we solved them already: Analyzer 2.5 (iOS8 only) is already in review at iTunes and will be available in a few days (hopefully). The In App purchases are compensations for microphone frequency responses. They are available everywhere! And I don’t think it is a problem to buy the microphones in Spain…

Hello Mika, we have the update for iOS 8 already in review at iTunes. It should be out there already but it seems the Apple people have other things on the list at the moment… We all need alittle patience there.

Hello Manuel,
please make sure that the Analyzer has access to the microphone in settings->Analyzer-> microphone. If it has access try this: – quit the Analyzer and all other audio apps by double pressing home button and up swipe.
– go to settings -> Analyzer -> privacy -> microphone -> and turn allowance off.
– start Analyzer again and quit it again.
– turn allowance for microphone use on again.
– restart the Analyzer

Just purchased your app yesterday. It worked on my iPhone 6 for about a day. I notice a very large decrepancy between my iPad and iPhone 6 in regards to spl. The ipad was about 20 db higher than the new iPhone 6. I was under the impression that this app would work accurately with the iPhone 6 internal mic for spl. Did not seem accurate at all. I believe the ipad was accurate. Now the app does not show any sound at all on the iPhone 6. It works on iPad. I tried all of the suggestions as far as turning on and off the mic,app and so forth. Please advise or update. Thanks

Hi
I’m running Analyzer on an iPhone 6. Was working fine but between tests the “response”, “weighting”, “hold”, “snapshot” etc. buttons along the bottom of the screen have disappeared. Not sure what I’ve done but how can I get them back?
Thanks

Just change my phone and put the app back in but can’t get any sound into the anayliser. It has acces to mic and it is turned on in the app and on the iPhone 5s but I get nothing. What do I need to do?

On my iPad 3 (ios 813) there is a very large decrepancy between built-in mic and headset-in with regards to the displayed levels . On my iPhone 4S (ios 813) the discreapancy is almost nonexistent.
Also, it seems to me that the overall gain is fluctuating quite a lot on my iPad – the graph is bouncing up and down i a manner common to all frequencies. Is there a bug of unstable gain in the iPad app?
Thirdly, I have experienced periods of heavy LF rolloff on my iPhone. It disappeared after closing the app with task manager and starting it again.
Hopefully these buggy behaviours will disappear with a new version of the app.

Hello,
the level issues should be solved with newly available Analyzer v2.6. The occasional occurence of LF rolloff hints to unstable measurement mode. We never expereienced this before – do you use Audiobus?
